These greenbelts are linked to a series of parallel institutions, the Ethnobotanic Research Centre (EBRC) is to greenbelts by means of the Apies River which begins in fulfill this function. It will serve as a place for plant research the Fountains Valley to the south of the city. Along the river through consultation with traditional healers and laboratory there are a number of ecological assests, these include; testing. The EBRC will act as an educational tool by exposing the Groenkloof Nature Reserve, Wonderboom Nature the importance of these medical systems, through this, the Reserve, Bon Accord Dam, the three ridges (Salvokop at culture that resides within this practice will be exposed.

Roads generally run parallel and perpendicular to the Apies River, with two highways, the N4 and the N1 forming the major axis. The N1 links Pretoria and Johannesburg to the South, with the N4 linking Pretoria to Hartbeespoort in the west and Witbank in the east. This axis continued from the micro axis in the city, formed by the crossing of Church and Paul Kruger street. This axis is repeated on a smaller scale within the city at Marabastad. The environment becomes more rural towards the north forming important regions of indigenous vegetation, which are linked to the city through the mentioned movement spines. These paths and nodes form the growth/gathering/trade cycle for medicinal plants for Pretoria and its surroundings. 003 CONTEXT Bon UAccordnivers Damity of Pretoria etd - Butcher, A (2003) r e v i R s 1 e N i p A Magaliesberg range Witwatersberg range Meintjieskop N4 PRETORIA CITY Salvkop 2.1 Apies River link to Pretoria 004 Skanskop Klapperkop University of Pretoria etd - Butcher, A (2003) 2.2 View south over Groenkloof nature reserve from Salvokop Salvokop Voortrekker Monument 2.3 View South over Pretoria from Union Buildings 2.2 Meso Analysis public transport nodes of Belle Ombre in the north and the 2.2.1 Green open spaces Pretoria train station in the south (See fig.2.4) Within the city there are a number of formal and informal 2.2.3 Cultural Installations green spaces The formal spaces are indicated in the open Places of cultural significance within the city are indicated in space map (See fig.2.4).
